The Snyder Industries 300 Gallon Plastic Horizontal Leg Tank (SKU SII-1321000C26) is a 300-gallon white polyethylene tank built on a horizontal leg-tank footprint of 38 by 68 inches and 44 inches tall. Its molded support legs let it sit level on a trailer or skid without a separate cradle, which is why farm and applicator crews reach for a horizontal leg tank when liquid has to travel. Snyder rates this tank to a 1.9 specific gravity, so it carries heavy fertilizer blends and dense chemicals that a standard 1.0-rated tank cannot legally hold.
Will it work for your load?
Fill it with water and you are at roughly 2,502 pounds. The 1.9 specific-gravity rating is what lets you push past that: at the rated maximum the contents alone can reach 4,754 pounds, so size your trailer axles, springs, and tie-downs for the loaded number, not the water figure. At 68 inches long and 38 inches wide it drops onto most utility and applicator trailers, and the 44-inch height keeps the center of gravity low while hauling. If you are weighing this against other sizes, run your gallons and product weight through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. For how these tanks fit DOT and agricultural-exemption rules on the road, see our guides on applicator and leg tanks for fertilizer and portable utility tanks under the 49 CFR 173.5 ag exemption.
Chemical compatibility
This tank carries an OEM-published 1.9 specific-gravity rating. The exact polyethylene resin designation in our data still needs confirmation, so verify HDLPE versus XLPE and its suitability with us before you put this tank into chemical service. The chemicals below are compatible at the listed concentrations when paired with the correct fitting and gasket materials; always confirm against the OEM chemical-resistance chart for your specific concentration and temperature. For EPDM-gasket service: Acetic Acid 60% (PP/PVC fittings, details), Aluminum Sulfate 50% (PVC, details), Calcium Chloride 40% (PVC, details), Ethylene Glycol 100% (PVC, details), Ferric Chloride 50% (PVC, details), Ferric Sulfate 60% (PVC, details), Ferrous Sulfate 20% (PVC, details), Magnesium Chloride 30% (PVC, details), Potassium Carbonate 50% (PVC, details), Potassium Hydroxide saturated (PVC, details), Sodium Carbonate 30% (PVC, details), Sodium Thiosulfate 40% (PVC, details), Urea Solution 50% (PP/PVC, details), DEF 32.5% (316SS fittings, details), and the unconcentrated chemistries Polyaluminum Chloride (PVC, details), Propylene Glycol (PP/316SS, details), Sodium Bisulfate (PVC/PP, details), Sodium Bisulfite (PVC/PP, details), Zinc Orthophosphate (PP/316SS, details), and Ozonated Water up to 10 PPM (PVC). For Viton-gasket service the chart lists Hydrochloric Acid 37% (PVC, details), Hydrofluoric Acid 48% (PP/PVC, details), Hydrofluosilicic Acid 26% (PP/PVC, details), Hydrogen Peroxide 50% (PVC, details), Phosphoric Acid 85% (PVC, details), Sodium Hypochlorite <16.5% (PVC, details), and Sulfuric Acid 98% (CPVC, details); Peracetic Acid 30% needs 316SS fittings with Aflas gaskets (details). See our full chemical compatibility resource to match your exact chemistry.
The mistake to avoid
The trap on a horizontal leg tank is matching the gasket and fitting material to the chemical, not just the tank. The same PVC bulkhead that handles ferric chloride will not protect you on hydrochloric or sulfuric acid, where you need Viton or CPVC. Specify the fitting and gasket material from the compatibility table above for your actual product, and confirm whether your blend may stratify in transit. If you are running fertilizer, our note on fertilizer-blend stratification covers how to catch a salted-out load before the spreader runs off-spec. If your chemistry falls under SPCC secondary-containment rules, our walkthrough on Snyder Captor double-wall tanks for SPCC 40 CFR 112 covers the containment path.
